A liquid mixture containing 30.0 mole% benzene (B), 25.0% toluene (T), and the balance xylene (X) is fed to a distillation column. The bottoms product contains 98.0 mole% X and no B, and 85.5% of the X in the feed is recovered in this stream. The overhead product is fed to a second column. The overhead product from the second column contains 97.0% of the B in the feed to this column. The composition of this stream is 94.0 mole% B and the balance T.
Still 1 Correct. Write three balances and use one constraint for the performance of Still 1 to solve for the following quantities for a process feed (₁) of 200.0 mol/h. First Still Bottoms flow rate (n₂) = 78.52 Overhead fow rate (n3) = 121.47 Benzene mole fraction in overhead (x3B) = Toluene mole fraction in overhead (x37) = mol/h mol/h 0.493 0.3986
Still 2 Write three balances and use one constraint for the performance of Still 2 to solve for the following quantities for a process feed (₁) of 200.0 mol/h. Second Still Overhead from second still (n5) = i Bottoms from second still (n4 ) = i Benzene mole fraction in bottoms from second still (X4B) = i Toluene mole fraction in bottoms from second still (x4T) =
